The official cut off date is October 1st, however lenders need lead time to process. So for Wells Fargo the date was August 15th.
The loan limits were raised by Congress in 2008 temporarily from $417,000 to $729,000 in the highest priced markets in order to help bring much-needed liquidity to the mortgage market after the sub-prime meltdown that sent investors fleeing. There has been heavy lobbying by the Realtors, mortgage bankers and home builders to extend the limits, but so far to no avail.
